It seems that this is a bug. When I look at TCustomSplitter.MoveSplitter there is a loop over all anchored controls that calculates a value CurMaxShrink. It seems that this routine only considers to "shrink" these anchored controls (when the splitter moves) but it is not taken into account to "move" these controls. That's a bug IMO. If a control cannot be shrinked but can be moved then this should work too. I have anchored some controls to the left which themselves have no anchor to their left side but their size is determined via AutoSize. They are "right aligned" so to speak. If I move the splitter to the left via code it works as expected and the anchored controls on the left are moved too. But when using the mouse then TCustomSplitter.MoveSplitter restricts the movement of the splitter to the "shrinkability" of the anchored controls only. -- _______________________________________________ Lazarus mailing list Lazarus@lists.lazarus-ide.org http://lists.lazarus-ide.org/listinfo/lazarus
